I've never had a problem at Jordon Park or Buck Creek, but then again I keep and an old beat up pickup truck attached to the old boat trailer all the time. Nobody is going to bother these old, but reliable beasts. Once while going out with a guide I even left my Charger's trunk open for the whole afternoon with many valuable tools, spare, etc. visible and ready for the pickin' and nothing was touched. Lucked out there.
